ABSTRACT: The aim of the study described in this paper was to develop a method for measuring the therapeutic alliance from an intersubjective perspective and to evaluate the efficacy of the measure in predicting psychotherapy outcome. We conducted the study using data from 22 patient-therapist dyads engaged in a 30-session protocol of a brief relational therapy. The alliance measure chosen for this purpose was the short form of the Working Alliance Inventory. We used the subjective patient and therapist versions of the measure and created a correlation index representing the intersubjective congruence between patients and therapists on their ratings of the alliance. We examined the relations among the measures, as well as their predictive relation to an outcome measure. The results showed significant intercorrelations among the three alliance measures, suggesting that all captured aspects of the therapeutic alliance. In addition, all three measures were significantly predictive of outcome, with the correlation index appearing more powerful.
